Hello Guys,
I am working with Event type of system. Where we have multiple dates for the same event like:

And the values are comma separated, like: 2017-06-03,2017-06-05,2017-06-07 and the data map is:
{
  "mappings": {
    "my_type": {
      "properties": {
        "event_date": {
          "type":   "date",
          "format": "yyyy-MM-dd"
        }
      }
    }
  }
}
But in this case the document is not able to index to elasticsearch.
Please help me, how I can index this and add the range filter?
